srnvmive APPARATUS Application filed Kay 2, 1928, Serial No. 274,579, and in'l'rance July 13, 1927.

This invention relates to spinning apparatus of the kind-in which the yarn 1s twisted by a driven flyer device and a winding-on device to which an adjustable drag 5 is applied, and the object of the invention is to provide an improved spinning apparatus of thistype. 7

According to the invention, the spinning apparatus comprises a flyer provided with 10 yarn guides mounted to slide freely in vertical 1 guides on the flyer so as to be capable of hanging on the yarn and a drag brake consisting of a freely mounted roller upon which a part of the bobbin bears.

The accompanyin drawing shows, by way of example, one. orm of the invention: The figure is a vertical longitudinal 'section of the complete device constructed ac cording to my invention. 2 In a cross bar 1 fixed to supports cast in one with the frame is tightly held a hard bronze collar 2 with lubricating cup. This collar is provided with oil ways 3 and 4.

Upon the u per shoulder of the collar and 25 cup rests the yer or winding tube 5 of cement steel, hardened and rectified at the part work ing in the collar and cup.

The flyer is fixed to a V- groove pulley 6 ofsuitable diameter, tap ed and tightly 30 screwed in the direction 0 rotation. This pulley is driven from a driving element known as a drum on which cords or bands are mounted in the usual manner.

On the lower end of the collar 2 is fixed a screwthreaded bronze ring 8 which serves to guide the flyer and at the same time forms the connection between the oil circulation conduits.

On the upper part of the flyer is mounted a guide ring 9 in which holes 10 and 11 are formed to receive yarn ides 12 and 13 which are adapted to sli e in the holes 10 and 11 whose weight is adjusted in accordance with the count of the thread as hereinafter explained. Below the holes, are arranged two guide ribs 14 and 15 which form grooves for maintaining the yarn guides in A place and for preventing them from pivoting on themselves. W Above the guide rmg 9 1S mountedanother guide ring 16 of bronze and this is also ormed with holes 10 and 11 for the yarn guides but if the count of the thread is such that very light yarn guides are required this element may beomit d.

The rings 9 and 16 can be adjusted and fixed by. means of screws 17 and 18 in the required position in a groove 19 formed in a suitable part of the flyer.

On the cross bar 1 is fixed a support 20 for the independent brake for the flyer. This support is fixed to the cross bar by means of a square headed screw 21 which also. holds I the collar by means of a bore-hole cut therein. Further, it is held in its fixed position by a pin 22. In the support is mounted a bush 23 with internal square screw threads and I against thisbush is another bush 24 with screw threads ad hoc.

The hand control 24 by means of two grub screws 25 and 26.

i The two bushes are connected by a threadved shaft 28 to one end of which is riveted a jaw 29 carrying a fibre or leather crescent 30.

On the lower cross piece 31 secured or fixed on feet or supports cast in one with the frame is fixed a vertical steel spindle 32 which is screwthreaded at its lower part. Under the shoulder on this spindle is di osed a gudgeon or prisoner 33. This spin le is fixed by two nuts 34 and35.

The n ward and downward movement of the plat orm is ensured by two vertical shafts or uprights 36 working in a bronze socket 37 provided with an oil cup and cut away at the upper part of its bo re.

The uprights may also be guided at their upper parts by means of a support provided with a bronze socket and fixed to the frame.

On a screw threaded part at the end of the uprights is fixed a support 38 and this support is held in machined shoulders" or collars 39 and 40 which hold the platforms41 firmly in 8osition. n the platform rests a shouldered bronze bush 43 in which is fixed the brass sleeve 44 which forms the intermediate part of the bobbin-carrier. This sleeve bears on the spindle at its ends only so as to diminish the friction between the contacting parts and at the same 27 is fixed to the bush time to form a lubricating chamber. On the upper end of this sleeve is mounted a threaded bush 45 on which'the bobbin 46 rests. At the bottom of the sleeve on the inside a cut is made to form a lubricating cup. A pin 40' adapted to be engaged in any one of ,four holes in the platform 41 holds the bush 43 against rotation. The bobbin moves freely on its spindle to follow the alternate move-' mentof the bobbin-carrier and its lower foot or flange must be turned to the exact shape steel. It is free on the spindle 48 and can move slightly up and down on the spindle for the purpose of eliminating wear. The bore of the roller is slightly widened at .one end to facilitate the flow of oil. The friction roller is held simply by the pin 49 which is forced into the hole 50 and bent upon itself above the spindle. The simultaneous rotation of the friction roller and the lower flange of the bobbin prevent wear of these elements.

The small spindle 48 may beforged and fitted in the piece or simply threaded before hardening and screwed into the upper shoulder 51v of the brake rod or bar 52.

If the brake is mounted by means of a steel rod of suitable section, the shoulder of the spindle is simply turned or shrunk onto the piece.

On the flanged bush 45 is fixed a slide 53 in which the brake bar 52 works. This slide is formed as a ramp to cooperate with a cam projection 54 on the brake bar.

A small sprin 55fixed in a groove 56 in the sleeve 44 an acting onthe brake bar 52 serves to press the cam projection 54 against the ramp'formed in the slide 53.

Further the guiding of the lower part of the brake bar is ensured by a slide piece 57 soldered to the slide 44. The brake bar is fixed at its lower part by a square piece 58 sliding in a groove formed in the bush 43. The bar and this piece are connected by means of two screws 59 disposed in the same plane.

In a slide 60 of the support 58 is placed a stop bolt 61 which passes through the piece 62 fixed in a groove in the piece 43 and held in position by the screwed pin 42. Onthe friction roller.

platform to serve as a support for a bobbincarrying spindle in order toensure facility,

for the s inning operative to replace the bobbins with empty ones as soon as they are filled. This support 65 carries a spindle 67 which is fixed by a nut 68. The replacement bobbin 69rests on the spindle shoulder and is disposed between each bobbin carrier conveniently to the hand of the operator.

In the operation of the apparatus, the spinning operative stops the winder by means of the hand brake at the beginning of the winding operation. Then she breaks off athread end' of a certain length from a 1 full bobbin and winds this by hand on the outer part of thebobbin. She then passes" the thread through one of the yarn ides and releases the winding brakelwit her right hand still holding the thread in the fingers of her left hand. She adjusts the drag by lightly braking the bobbin through the roller by the regulating screw and assoon as she feels that the reaction of the said roller is sufficient for normal winding without undue tension she makes the connection.

She then makes the final adjustment to bring the thread coming from the cylinder to the level of the scrolls with her right hand whereupon she tightens the set screw of the regulator. The bobbin is then wound nors mall to the end even if there are accidental breaiages as the balance between the effort and resistance is always ensured by the o posing and instantaneous reaction of fie In setting up the apparatus after the two cross bars have been fixed exactly in a vertical plane, the trued-spindles 32' are engaged I in the feathers in the lower cross bar and fixed by means of the nuts 34 and 35. Then the sockets 37 are mounted and the u rights 36 setup after which the supports or. the platform 38 are screwed in the The platforms 41 are then placed on their supports. p c

To mount the bobbin carrier, it is only necessary to introduce the brake bar into the slide 53 afterhaving first placed the springs 55- in position, screw the sleeve 44 to the bush 45 and then screw the lower end of the sleeve into the socket 43 in its thread, fix the support 58, place the square 62 in po sition an brake regulating mechanism.

The brackets 65 for the replacement bobbins and also the spindles 66 canthen be set up.

The collars 2 are then fixed in the upper cross bar 1. This latter mustbe mounted wih great'care. The winders 5 with their rings 9 and 16 are placed'in position and then the lower nuts of the collars and the V-pulleys are screwed on. The yarn-guides 12 and 13 are placed in position and the supports for the winding brake 20 are -set up connect it to the bolt 61 of'the arrangement, the winding angle is straight and also the screwed bushes 23 and 24, the handle 27, the spindles 28 and jaws 29 and the fibre or leather crescents 30.

This arrangement is of simple design and is free from vibration and has the maximum protection from centrifugal reaction by reason of its position and form. Its true vertical mounting, the ease with which it can be balanced and its rotation on parts which are strictly aligned in a bronze collarwhich provides for lubricating by continual circulation of oil permits of Very high speeds without fear of heating of the contacting parts.

The vertical position of the tube also enables the machine to work all day without stopping, the removal of the bobbin when filled being effected in one operation and without any difiiculty by the use of the individual brake which is placed ready to hand at the lower part of the tube.

In the position which it occupies in this ened to themaximum degree and this position considerably reduces the effect of centrifugal force on the yarn.

The slight ballooning which can still take place under conditions of very high speed in the parts which are not guided can be exactly balanced at the desired elastic tension by the practical determination of the weight of the yarn guides which are movable GASTON VAN COPPENOLLE.

and capable of regulation and which work freely in bronze slides which are capable of displacement in a groove and are fixed by means of a screw as shown in the accom- 'panying drawing.

It 1s also possible, notwithstanding the short distance between the delivery cylinder and the scrolls due to the free vertical posi-' tion of the tube, to interpose a movable thread guide very near to the extreme winding point thus almost completely preventing ballooning at the greatest speeds of rotation of the 'tube.

The tube is driven in the usual manner by means of a tin roller and V-pulley and the direction ofrotatlon can easily be reversed to produce reverse twist by simply crossing the driving ropes or bands.

The bobbin carrier follows the alternating movement of the carriage which is controlled in the usual manner by a heart cam with balancing counterweights or by a piece known as a lantern.

The arrangement as designed is not dangerous and cannot cause an accident when working in spite of the high speeds which can be attained.
